just a little confused ?

In the beginning of April my boyfriend and I had unprotected sex and he came inside of me for all the 4 days we had sex. I gotten my period not even 5 days after we stopped having sex I have very irregular periods I tested and got a BFN could I have tested to soon? I know since I got my period it's likely to be a BFN but with how irregular my periods are. And then I was back visiting him a few days ago according to glo it was the beginning of my fertile week and he again came inside of me all the times I was with him for the 3 days straight and I know it was only 5 days ago but my uterus feels so hard I can't stop eating I've been so tired nauseous and also sorry for the tmi but I've been so wet the day after I returned to my current home I woke up and it felt like I kinda peed myself like when I got up to use the bathroom it was dripping ? Everything down there feels fine besides the hardness and no order so I'm confused and don't know what to think
